Intro

I liked the Financial Times plots for tracking the evolution of COVID-19 (https://www.ft.com/coronavirus-latest), but then they changed to different plots. So here I am more-or-less reproducing those plots (and adding some others).

Grab data

I’d like to find an easy source of online data that breaks down the US by state, but for now just use the country data from ourworldindata.org:

cases = read.csv("https://covid.ourworldindata.org/data/ecdc/total_cases.csv",
                 stringsAsFactors=FALSE)
cases$date = as.POSIXct(cases$date)

deaths = read.csv("https://covid.ourworldindata.org/data/ecdc/total_deaths.csv",
                  stringsAsFactors=FALSE)
deaths$date = as.POSIXct(deaths$date)
